Description

Technical Field

[0001] This utility model belongs to the field of automotive air conditioning system component manufacturing technology, and in particular relates to a D-dimensional gauge for the refrigerant circulation pipeline from the compressor to the condenser. Background Technology

[0002] The automotive air conditioning system consists of heating, cooling, air purification, and control systems. The cooling system comprises a refrigerant (evaporator), compressor, condenser, expansion valve, receiver-drier, and connected high and low pressure refrigerant circulation lines. Its main function is to regulate and control the temperature and humidity of the air entering the vehicle cabin from either the interior or exterior. The circulating refrigerant within the system exchanges heat through the refrigerant (evaporator) and condenser, absorbing and dissipating heat from the air passing through the cabin, thus providing a comfortable driving and passenger environment.

[0003] The flexible high-pressure pipe assembly for heavy-duty truck air conditioning—from compressor to condenser D—is a key component of a heavy-duty truck air conditioning refrigeration system. It is the high-pressure pipeline component connecting the compressor and condenser in the refrigeration system. Due to the different installation locations of the refrigerant (evaporator), condenser, expansion valve, and compressor in automotive air conditioning systems, as well as space constraints, the refrigerant circulation pipelines connecting them are very tortuous and complex. Therefore, the designed pipeline routes are also varied and winding. Using conventional measuring tools to inspect dimensions during manufacturing presents many difficulties, makes it hard to guarantee product consistency and dimensional accuracy, and is very time-consuming, affecting production progress.
